Use simple asserts and pytest's powerful introspection to make testing simpler. This merges the old .py/.ref file pairs into simple .py files where the expected values are right next to the code being tested. This commit does not touch the C++ part of the code and replicates the Python tests exactly like the old .ref-file-based approach.
